If you're getting numbness and tingling, you should see a neurologist. Someone in physical medicine and rehabilitation or in orothopedics would be good choices as well. Radiating pain suggests that a nerve is being irritated or pinched somewhere. They might do an xray, MRI, and/or an EMG (tests nerve conduction and function). There could be something wrong with the spine causing irritation of the nerve. There might also be severe muscle tightness irritating the nerve. And pain has a way of building on itself, and is usually worsened by depression (and vice versa). Stress can certainly make you twitch, but it doesn't cause radiating pain and tingling.
